Final answer:
The individual with principal responsibility for derivative classification accuracy in new products would be someone with training in classification procedures and direct involvement, typically a product manager or similar role, not necessarily any of the listed executives.
Step-by-step explanation:
The individual who bears principal responsibility for derivative classification accuracy in new products is not explicitly mentioned among the provided options. However, responsibility for classification generally falls on individuals who have direct involvement with the sensitive content and are trained in classification procedures. While all members of an organization might share in the responsibility for safeguarding classified information, it's typically individuals with the appropriate training in handling such information, such as product managers or others with security training and delegation, who would be responsible for derivative classification accuracy.
In a broader sense, executive leadership, such as the CEO, would ensure that proper policies and training are in place; however, operational responsibilities would more likely be delegated to positions that directly interact with the classified material on a day-to-day basis.
